This CL changes "MessageWriter" type to std::function instead of a plain function pointer. This allows capturing lambdas, which in turn are used to make unittests more robust.

Trap handler registration happens under a spin lock, which causes lots of wasted cycles. With 48 background compilation threads, half of the wall-clock time is being spent on that spin lock. Moving this registration inside {PublishCodeLocked} avoids any lock contention (if a single module is being compiled), since we already sequentialize code publication. This speeds up background compilation for large numbers of background tasks, and has no measurable effect for small numbers.

CompressedHeapConstant is used in the DecompressionElimination Reducer to create compressed HeapConstant values. It won't appear in the graph up until that point. This CL enables back the disabled tests in DecompressionElimination, as well as generating the CompressedHeapConstant in that reducer. The RelocInfo has already been added for x64 but not for arm64. Therefore, the x64 version is now doing the mov on 32 bits. The support for ARM will come in a following CL, and for now it is doing the mov in 64 bits.

Array push / pop / shift were inlined if the elements kind of the receiver maps is the same. This cl extends it by inlining these builtins even when the receiver maps have different elements kinds. It still limits it to only fast elements kinds. This is required to prevent regressions in deltablue when lazy feedback allocation is enabled. With lazy feedback allocation we may see polymorphic feedback more often, since we don't have allocation site feedback till the feedback vectors are allocated.

This fixes a problem where ICs for transitioning stores go MEGAMORPHIC if the transition target map dies in between invocations of the IC, which is totally possible, since we only hold on weakly to these transition targets (both from the FeedbackVectors and also from the TransitonArrays). The root problem here was an inconsistency in how the maps and handlers are being reported by the FeedbackVector. On the on hand side the method FeedbackVector::ExtractMaps() will report all receiver maps that are still present (i.e. which haven't died themselves), but then the other method FeedbackVector::FindHandlers() will only report handlers that are still alive (i.e. which in case of transition target maps being used as handlers haven't died yet). If the length of these lists don't match the IC chickens out and goes MEGAMORPHIC. But this is exactly the case with the transitioning stores, where there's no handler anymore, i.e. as can be seen in this simple example: ``` // Flags: --expose-gc function C() { this.x = 1; } new C(); new C(); gc(); // map with the `C.x` property dies new C(); // now the STORE_IC in C goes MEGAMORPHIC ``` So the problem is that we have these two methods that don't agree with each other. Now FeedbackVector::ExtractMaps() is also used by TurboFan and it even reports receiver maps for PREMONOMORPHIC state, which is different from the use case that the ICs need. So I replaced the FeedbackVector::FindHandlers() with a completely new method FeedbackVector::ExtractMapsAndHandlers(), which returns both the maps and handlers, exactly as the ICs need it. And only returns pairs for which both the receiver map and the handler are still alive. This fixes the odd problem that sometimes STORE_ICs going MEGAMORPHIC for no apparent reason. Due to the weakness of the transition target maps, they can still die and cause deoptimizations, but at least TurboFan will now be able to reoptimize again later with the new maps and still generate proper code.

The size is now computed as a fraction of the old space size: - for low memory devices (<512MB) the fraction is 1 / 256. - for all other devices the fraction is 1 / 128. The values were chosen to minimize the difference between the new and the old heuristics.

Without this, asan (rightfully) complains about read-only space leaking. Because pages are manually allocated using mmap, a few objects within them need to be explicitly ignored in addition to the read-only heap itself.

The `FunctionTemplate::SetHiddenPrototype()` API was removed in a previous CL, after being deprecated since beginning of the year. This removes all the logic behind it, leaving us with just the special case of the JSGlobalProxy which has the JSGlobalObject as its hidden prototype. This gives us back one bit in `Map::bit_field2` and removes quite a bit of complexity from the code base (especially due to previous work from verwaest@ in this area).

Currently, Number.prototype.toString(radix) often fails to produce the least significant bit for doubles near zero. For example, for the minimum double, 5e-324, toString(2) produces "0". This means that a user cannot reliably get the exact binary or hexdecimal value of a double from JavaScript using toString. This patch makes a slight amendment to the DoubleToRadixCString function, so that doubles where the gap to the next double is 5e-324 (i.e. doubles less than 2**-1021), are represented exactly in binary and other power-of-two bases, and close to exactly otherwise. It results in Number.prototype.toString producing the correct binary value for all doubles.
